So what this means is that Tityus is vulnerable to full linear aim? I have sort of figured that out already. But it's good to have a test bot that I can use to make sure the next version isn't. Thanks! -- PEZ

Be wary that as posted it uses low power bullets (fire(1)) so don't expect 8% or less hitrates - it's a very simple modification to change that, though. DT 1.91 in challenge mode gets about 11.6% hitrate against from this gun, and that results in no wins for the linear tester. -- Kuuran
